Disgusting customer service that has cost me __A<<150

I called expedia to change my flight booking because their online systems wouldn't allow it. I have spent over 2 hours on the phone being put on hold with 2 dropped calls and my flights have still not been changed. My call costs are currently sitting at 150 euros (with the calls needing to be international) and my flights have still not been changed. I have complained on numerous occasions while on the telephone and all it has resulted in is being put on hold. And while all this is happening, its getting closer to my original flight date and the actual flight is getting more expensive. Disgusting. I don't recommend expedia to anyone. It is a helpless situation that they put you in and there is nothing I can do. Their customer service is the worst I've ever received and on top of this there are no complaint lines online, so there is NOTHING I can do. My phone bill has cost me almost the price of an actual flight. I am beyond angry and absolutely disgusted. <br> <br> If expedia wants to contact me they can check online for my email address. My itinerary number is ***.
